Plot of range against mean.
rmg (vari, krmg)
vari |
a ts object. |
krmg |
the number of observations in the intervals in which the the range and mean are calculated. |
In order to ensure that enough observations are employed for calculating each point,
it may choose a choose a value of krmg
based on the number of observations N, for example: sqrt(N).
A graphic of the range against the mean, and the correlation between the range and the mean.
